Problem
Mining and fertilizer production generate substantial sulfate waste byproducts, posing environmental and economic challenges. Traditional sulfuric acid production relies on fossil fuels, contributing to carbon emissions. There is a growing need for carbon removal and sustainable building materials to decarbonize industries like cement production.
Solution
Travertine employs a process that integrates direct air capture (DAC) with mineralization to transform carbon dioxide into carbon-negative building materials. This process also recycles sulfate byproducts from mining and fertilizer industries, converting waste into valuable resources. The technology offers a fossil-free method for producing and recycling sulfuric acid, a widely used industrial chemical. By capturing CO2 from the air and permanently storing it in building materials like precipitated calcium carbonate (PCC), Travertine contributes to carbon removal and can help decarbonize cement production. The process can optionally co-produce green hydrogen, further supporting the energy transition.
Target Audience
Travertine's primary customers include mining companies, fertilizer producers seeking to eliminate sulfate byproducts, and construction companies looking for carbon-negative building materials.
